We recently moved to an internal Exchanger Server 2007 for mail. Our domain is registered with GoDaddy. Everything is working fine for the most part with the exception of some delayed incoming mail. I ran a test on my Exchange server which ha told me Port 587 did not respond.
I have read I must configure a smarthost.
In Org Conf -> Hub Transport -> Send Connectors Tab -> Default Send Connector properties -> Network Tab it is configured to Use domain name system [DNS] "MX" records to route mail automatically.
For my receive connector, the SMTP service is disabled on the Exchange server as it was causing a problem receiving any mail. When disabled it works, for the most part with some delays.... I read somewhere I must configure IIS SMTP Virtual Server smart host. IIS -> Default SMTP Virtual Server properties -> Delivery Tab -> Advanced -> Smart Host
What has been told to me, that I should use smtpout.secureserver.net as the smart host, is this true even though i removed these records from my GoDaddy DNS settings and only use mail.mydomain.com ??
Also, when the settings is set in IIS, do I start the SMTP service on the server? If I start the service will mail be stopped again, or work properly and fast with no delay?
Your help is greatly needed.
